The bill introduces a new section to chapter 36.01 of the Revised Code of Washington (RCW) that mandates counties to collect and maintain records of public works activities. Specifically, counties are required to document any removal of natural or organic materials, such as soil, trees, and gravel, during these activities. The records must include the quantity of materials removed, their disposal locations, any reuse for other projects, and whether they were tested for contaminants along with the results of those tests.

Additionally, the bill defines key terms to clarify its provisions. "De minimis amount" refers to a quantity of material that is too small to be easily noticed without detailed examination, while "public works activity" encompasses maintenance or construction work conducted by the county on roads adjacent to privately owned properties. This legislation aims to enhance transparency and accountability in county public works projects by ensuring comprehensive documentation of environmental impacts.
